SP3-xxx: Process

3001* ID Sensor Initial Setting
3001 1 ID Sensor PWM Setting
Allows you to reset the PWM of the ID sensor LED to avoid a service call error
after clearing NVRAM or replacing the NVRAM.
The PWM data is stored by executing SP-3001-2.
3001 2 ID Sensor Initialization
Performs the ID sensor initial setting. ID sensor output for the bare drum (V
adjusted automatically to 4.0 ±0.2 V.
Press "Execute" to start. Perform this setting after replacing or cleaning the ID
sensor, replacing the drum, or clearing NVRAM.
3103* ID Sensor Output Display
Displays the current V
If the ID sensor does not detect the ID pattern, "V
displayed and an SC code is generated.
If the ID sensor does not detect the bare area of the drum, "V
V" is displayed and an SC code is generated.
3103 1* Vsg (Drum Surface Output)
3103 2* Vsp (Pattern Output)
3103 3* Vsdp (Immediate Post-Pattern Output).
3103 4* Vsm/Vsg (Grayscale Post-Pattern Output)
3905* Hot Roller Stripper Cleaning After Job
Toner and carbon clinging to the hot roller strippers can cause poor print quality.
To prevent this, toner and carbon are dislodged from the hot roller strippers in two
ways: 1) switching the fusing motor on/off after every print job, and 2) freely
rotating the hot roller for 5 s at the beginning of every print job. These SP set up
operation of the first method (switching the fusing motor on/off after a print job.)For
details, see Section "6.6.2 Hot Roller Stripper Cleaning". Also see SP 5959.
3905 1* Number Rotations
This SP sets the number of times the 1st Cleaning is done for the number of
pages prescribed with SP3905 002 have been printed.
[0.0~1.0/1.0/0.1]
Note:
•
All fans remain on during cleaning and then switch off 60 sec. after the
cleaning cycle ends.
•
Raising this setting can increase wear on the hot roller and cleaning roller and
shorten the service life of the hot roller.
3905 2* Number of Pages
This SP prescribes the number of pages to accumulate before the fusing motor is
switched on/off (1 cycle).
[0 ~ 1000 / 5 / 1]
Unless you change this setting, 15 sec. after a total of 5 pages have been printed
(the accumulated total of several small jobs), the fusing motor will switch on for 15
sec. and then switch off. This 15 sec. off/15 sec. on at the end of a cleaning job is
the 1st Cleaning.
